Glucose Tolerance Test (8 Samples)

This test evaluates how effectively your body handles glucose, a form of sugar and a vital energy source. Monitoring blood sugar levels after consuming a glucose solution helps in identifying diabetes or any sugar metabolism issues.

• To diagnose diabetes or gestational diabetes
• To detect impaired glucose tolerance
• To evaluate hypoglycemia
• To assess insulin resistance
• To diagnose reactive hypoglycemia
• To identify pre-diabetes

Doctors recommend this test if you:

• Have symptoms of diabetes like increased thirst, frequent urination, and fatigue.
• Are at high risk due to obesity, a sedentary lifestyle, or a family history of diabetes.
• Are pregnant with risk factors for gestational diabetes.
• Need monitoring for prediabetes or insulin resistance.
• Have had abnormal blood sugar results in routine testing.

Abnormal results may indicate diabetes, impaired glucose tolerance, pre-diabetes, or gestational diabetes. The results should be discussed with your doctor for further evaluation and management.

During this test:

• You will fast overnight before ingesting a glucose drink.
• Blood samples will be taken eight times, at various intervals, for glucose measurements.
• You may feel nausea or dizziness due to the glucose drink

Prepare for the test by:

• Fasting overnight before the test.
• Not smoking or exercising before the test.
• Informing your doctor about all medications you are taking.
• Ensuring no recent illness or stress that can affect blood sugar levels.
• Following the specific instructions of your healthcare provider.

• HbA1c Testing: Measures average blood sugar levels over three months.
• Fasting Plasma Glucose Test: Assesses blood sugar levels after an overnight fast.
• Oral Glucose Tolerance Test: Evaluates how your body processes glucose after consumption.

GTT or Oral glucose tolerance test

Diabetes is a condition where blood sugar levels are consistently high due to either inadequate insulin production (Type 1) or ineffective use of insulin (Type 2). It leads to high blood sugar levels, causing symptoms like increased thirst, frequent urination, and fatigue. Management involves lifestyle changes, medication, and monitoring blood sugar levels regularly.
